HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 7 37,999, datedSeptember 1, 1903.

Application filed February 9, 1903 Serial No. 142,597. (No model.)

To whom it may concern:

Beit known that LGHAELEs CANNOM, a citizen of the Dominion of Canada,residing at London, in the Province of Ontario, Canada, have inventednew and usefullmprovements in Hydrocarbon-Burners, of which thefollowing is a specification.

This invention relates generally to hydrocarbon-burners and specificallyto that class employed in connection with domestic implements, such assteam-cookers or the like.

The object of the invention is in a ready, simple, thoroughlyfeasible,and practical manner to overcome danger of fires or explosions in theuse of gasolene as a heating medium, to conserve its use, to obviatewaste when the burner is not in use, to secure the maximum of heat unitsfrom the minimum of fuel consumed, and generally to improve, simplify,and render more efficient burners of this character.

The objects above stated are secured by dispensing with the employmentof elevated tanks for containing the gasolene, the supplying of liquidgasolene to the burner-head, and the complete elimination of leakage andwaste, with attendant danger of fire, as frequently results fromimproperly-fitting cock joints and valves. The results attained aresecured in part by conveying liquid gasolene by capillary feed to apoint adjacent to the burner-head and thence in vaporized form to thehead, where it escapes in gaseous form and is ignited. Furtheradvantageous results are secured by having the areas of the gas-supplyopenings communicating with the burner-head of so much greater area thanthe combined areas of the gas-escape openings as to create always apressure within the burner-head, whichoperates to cause the gas to beexpelled with considerable force, thereby producing a plurality oflong-pointed flames, which by impinging the utensil containing thematerial to be heated will cause it rapidly to be brought to the desireddegree of tempera- Furthermore, the relatively high pressure of thevapor or gas within the burner-head will operate to cause the gas-escapeopenings to remain free from any material that would operate to clogthem, so that careful attention to the burner-head is renderedpractically unnecessary.

With these and other objects in view, as will appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and combination of parts of a burner for hydrocarbon, aswill be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification andin which like characters of reference indicate corresponding parts,there is illustrated one form of embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theelements therein exhibited may be varied or changed as to shape,proportion, and exact manner of assemblage without departing from thespirit thereof.

In the drawings, Figure 1 is a view in elevation, partly in section, ofa stove having a burner or lamp constructed in accordance with thepresent invention disposed thereon, the burner-head of which is insection. Fig. 2 is a view in plan of a burner-head with the cap'removed.

Referring to the drawings, A designates a stove-casing, which may be ofthe usual or any preferred construction, in which is removably disposedthe burner or lamp of this invention, comprising a body or reservoir 1,which may be constructed of any suitable material, preferably of sheetmetal, a wick-tube 2, detachably connected therewith, and the burner 3.The burner comprises a head 4, preferably circular in plan and providedwith a tubular extension or neck 5, into which the upper end of thewick-tube is adapted to fit. The upper side or face of the head isapproximately cone-shaped and is reduced in thickness adjacent to itsperiphery to present a shoulder 6, against which is adapted to bear theinner face of the marginal wall or flange 7 of the cap, the periphery ofthe cap, as also that of the head, being projected laterally somedistance beyond said flange to present flame-deflectors 8 and 9, asclearly shown in Fig. 1. The top of the cap is flat, and adjacentthereto is a series of gas-escape orifices 10, of which there may be anydesired number, these orifices being of small diameter in order topresent resistance to the escape of gas, and thus prevent waste, and atthe same time to enhance the projecting properties of the flames or jetsto cause them to be driven the opening 13 is a series ofcircularly-disposed orifices 14, through which the gas escapes into thevaporizing-chamber, which is composed of the head of the cap thereof,and

thence escapes through the openings 10, as.

has already been described.

In order that the discharge of the gas from the openings 10 shall beintensified, for the reasons before stated, the combined areas of theorifices 14 are greatly in excess of the combined areas of the openings10, so that there will always be a volume of gas seeking exit which willbe held back through its inability to escape through the openings 10 ina volume greater than desired, and this backing up or accumulation ofgas within the vaporizing-chamber will cause a sufficient pressure to begenerated to effect rather violent escape of the gas. By reason of theconeshaped top of the head the incoming gas will be caused to impingethe under side of the cap, owing to the fact that the apex of the headis adjacent thereto, and is thence deflected laterally, and thisarrangement constitutes, in fact, an equalizing-chamber to effect equaldistribution of the gas to all of the escape-openings 10. The wick 15terminates a short distance below the top of the wicktubesay one-eighthof an inch-so that there is space provided to permit the vaporized fluidto spread and escape equally through each of the feed-orifices 14.

In the use of the burner a torch containing gasolene is ignited and isheld beneath or close to the head 4:, whereupon the contained air willbe driven therefrom and a vacuum will be set up, which will operate todraw the vapors from the upper end of the wick into the head, and as thehead becomes heated from the torch these will be vaporized and willescape in the form of a gas. After the gas is once ignited the head willbecome heated and will operate in a manner that will be well understoodto effect proper vaporization of the fluid. It will be noted thatcapillary feed is relied upon to conduct the fluid to a point adjacentto the head, and its conduction thence into the burner-head and withoutthe same is secured by vaporization. By thus utilizing the gasolene,danger of waste from dripping or explosion is positively obviated,

and all of the gas generated will be conserved to accomplish effectivework.

If at any time the gas-escape openings 10 should become clogged, as froman accumulation of carbon, this may readily be removed by employing astiff brush or a fine wire; but

it this fails to dislodge such accumulated matter the cap may bedetached from the head and placed in a coal fire until red-hot, when anysuch obstructing material will disappear.

Having thus described the invention, what I claim is 1. In a device ofthe class described, a burner comprising a head provided with aplurality of gas-inlet openings and with a cone-shaped upper face, and acap provided with a plurality of gas-escape openings, the combined areasof the gas-inlet openings being in excess of the combined areas of thegas-outlet openings, thereby to maintain a pressure within the head.

2. A device of the class described comprising a head provided with aplurality of concentrically-disposed gas-inlet openings, the

periphery of the head being reduced to present a circumferentialshoulder, a cap having its inner face in engagement with the shoulderand provided with a plurality of gas-escape openings, and a removableassembling device disposed centrally of the cap and of the head.

3. A device of the class described comprising a head provided with aplurality of gas-inlet openings and having its upper face coneshaped andits lower face provided with a tubular neck, a cap detachably connectedwith the head and provided with gas-escape openings, and a wick-tubedetachably connected with the neck, and disposed some distance below thegas-inlet opening.

4. The combination with a wick-tube, of a wick having its upper endterminating below the like end of the tube, and a burner comprising ahead having a tubular neck to engage the tube and provided with aplurality of inletopenings and with a cone-shaped upper face, and a capdetachably connected with the head and provided with gas-escapeopenings.

In testimony whereof I have hereunto set I re my hand in presence of twosubscribing witnesses.
